Abstract
An apparatus for measuring the temperature of a fluid flowing within a body comprising an elongated tube sized to be received within a vein or an artery and having a peripheral wall, at least one lumen extending longitudinally within the tube and an opening in the peripheral wall which extends from the lumen to the exterior of the tube. A thermistor is mounted in the lumen adjacent the opening by a thermistor mounting body. The thermistor mounting body cooperates with the tube to at least partially define a cavity at the opening which opens radially outwardly. The thermistor is partially in the mounting body and projects radially outwardly of the mounting body into the cavity so that the portion of the thermistor which projects into the cavity is in good heat transfer relationship to the fluid flowing within the body. The thermistor has a major axis and a minor axis, and the major axis is generally transverse to the direction of the flowing fluid. The tube has a body line, and the thermistor extends radially outwardly no farther than about the body line.
